Equilateral.
It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.
A rhombus can be split into 2 isosceles triangles or divided into 4 right angle triangles
Any right-angled triangle
Isosceles triangles
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
An EQUILATERAL Triangle. Two lines of symmetry is ISOSCELES Triangle No lines of symmetyry is SCALENE Triangle.

A scalene triangle is a triangle with no equal sides
right triangle ( triangles with a right angle)
It is an equilateral triangle that has 3 lines of symmetry
The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
A rhombus can be split into 2 isosceles triangles or divided into 4 right angle triangles
Any right-angled triangle
Isosceles triangles
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
